String Regular Expressions

[timgerr]

Hey all, I have a question for ya, Can I string together regular expressions?

Here is what I mean, lets say that I want to search for a valid email address that is 5 characters. Now I think that the email address would look like this

\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

and I would also want to make sure the email address is nore more than 25 characters. Can this be done with the same regular expression?

Thanks,

valid email address that is 5 characters

5 chars total?
5@5.5 which would be 15.

length ($emailAddress) for your last question.

yea but I was wondering if I could search for email address and no more than 5 characters within one regular expression

I'm still not following; are you looking for the first 5 chars of an e-mail address? if so, substrings are what ur looking for.

k, u don't necessarily needs regEx for that, just use the length funciton i.e

@emailArray = qw (data in here);
foreach $emailAddress (sort @emailArray) {
print "$emailAddress is gt > 25 chars\n" if length($emailAddress > 25);

This is not tested of course.

Max1x, thanks for the useful information. I know that I can do this by using other means, I was wondering if I could string multiple regular expressions to qualify a string.

Can it be done, if so are there any examples.

Thanks for the help,

Yes. for ex:
/()/i
$1 would represent whatever is inside the (); it could be you entire concatanated RegEx.
